Bootstrap 3, the popular HTML5 front-end design framework (and top-starred project on GitHub), has finally been released—and what a release it is! With tons of new features and a revised API, there’s much to enjoy. Here are some of the new features and things to keep in mind when working with Bootstrap 3.

Mobile-first and fully responsive
The Bootstrap 3 framework has been entirely rewritten to follow mobile-first design principles, so you can more easily build responsive web experiences that adapt gracefully from smaller to larger screens.

Recently I’ve been using a really awesome framework called Bootstrap to put small websites together. In this article, I’m going to guide you through the basics of the Bootstrap installation process, and how the Bootstrap framework can be customized for a responsive web design.

Why Bootstrap?

Bootstrap is a framework that provides an easy-to-use 12-column grid system for a 940 pixel wide container as well as a fluid layout grid that adjusts to the size of a browser. Included in the framework are customizable, well documented features—such as dropdown menus, buttons, tabs, breadcrumbs, modals, tooltips, and carousels—that can be implemented without any handwritten JavaScript.
